There is association between sleep quality and arterial blood pressure, but it is still unclear if the association also exists in the very elderly. We examined the individual association between sleep quality and arterial blood pressure among the very elderly.
MATERIAL/METHODS: The present study analyzed data from a survey that was conducted on all residents aged 90 years or older in a district with 2,311,709 inhabitants in 2005. Sleep quality was measured using The Pittsburgh Sleep Quality Index (PSQI).
The subjects included in the statistical analysis were 216 men and 444 women. There were no significant differences in sleep quality scores, sleep latency, and sleep efficiency percentage and prevalence of poor sleep quality between subjects with and without hypertension. None of the differences in systolic blood pressure, diastolic blood pressure, and prevalence of hypertension, systolic hypertension and diastolic hypertension among subjects with well, fairly and poor sleep quality were significant. Multiple logistic regressions showed that unadjusted and adjusted Odds Ratio (ORs) of poor sleep quality for increased risk for hypertension were significant.
Among very elderly subjects, there was no association between sleep quality and arterial blood pressure.
睡眠质量与动脉血压之间存在关联，但在非常高龄人群中是否也存在这种关联尚不清楚。我们研究了非常高龄人群中睡眠质量与动脉血压之间的个体关联。
材料/方法：本研究分析了 2005 年在一个拥有 2311709 名居民的区进行的一项针对所有 90 岁及以上居民的调查数据。睡眠质量使用匹兹堡睡眠质量指数（PSQI）进行测量。
纳入统计分析的对象包括 216 名男性和 444 名女性。在高血压患者和非高血压患者之间，睡眠质量评分、睡眠潜伏期和睡眠效率百分比以及睡眠质量差的患病率均无显著差异。在睡眠质量良好、相当和较差的受试者中，收缩压、舒张压和高血压患病率、收缩期高血压和舒张期高血压之间也没有显著差异。多因素逻辑回归显示，未经调整和调整的睡眠质量差的比值比（OR）与高血压风险增加相关。
在非常高龄的受试者中，睡眠质量与动脉血压之间没有关联。
